Could this be further proof that a baby Bey is on the way?

Beyonce just canceled her Tuesday night concert in Belgium due to "exhaustion and dehydration", her rep confirms.

According to her publicist's statement, the Grammy winner has been advised by her doctors to rest, so the show will be rescheduled and tickets will be refunded. She has another scheduled concert Wednesday at the same arena, but the singer is awaiting her doctor's professional opinion before deciding whether or not to take the stage.

"Dehydration and exhaustion" is a common excuse Hollywood stars use when they are trying to hide the truth of a situation, so could those pregnancy rumors actually be true?

Reports circulated this week that the "Love on Top" songstress is expecting her second child with husband Jay-Z after photos surfaced of her sporting what looks like a small baby bump during a performance.

Let the guessing games continue!
